Description

Technical Field

[0001] This invention relates to the field of photovoltaic tile installation technology, and in particular to a quick-install fastener and a photovoltaic tile. Background Technology

[0002] Photovoltaic tiles are a type of BIPV (Building Integrated Photovoltaics) product that deeply integrates photovoltaic cells with building tiles. They combine the functions of power generation and building materials, and can directly replace traditional tiles without requiring additional land or space. The overall system's power generation efficiency is close to that of traditional photovoltaic modules. By absorbing 20% ​​of the light energy and converting it into electrical energy, it reduces the accumulation of heat on the roof. In summer, the roof temperature is 10-15℃ lower than that of ordinary roofs. It is suitable for pitched roofs such as villas, industrial plants, and public buildings, and is especially suitable for projects with high requirements for architectural aesthetics. During the installation of photovoltaic tiles, there are quick-installation fasteners, the main types of which include adjustable hooks, quick-installation clamps and prefabricated support fixtures. Among them, prefabricated support fixtures are the most suitable fasteners for rapid construction. The embedded parts, prefabricated beams and installation frames are laid along the roof slope direction. Then, the photovoltaic tiles are hoisted to the designated position using a tower crane. Bolts and other fasteners can then be used to complete the combination connection between the installation frame and the photovoltaic tiles. However, in actual installation, in order to adapt to the shape of the mounting frame, traditional photovoltaic tiles are mostly equipped with rectangular strip purlins on both sides that match the mounting frame. The purlins are embedded into the mounting frame and then fastened with bolts. This bolt point contact fixing method results in a small contact area between the fixing component and the photovoltaic tile, and the stress is concentrated at a single point or local area, resulting in uneven stress distribution. This can lead to local deformation or even cracking, affecting the service life and installation stability of the photovoltaic tile. Summary of the Invention

[0003] The purpose of this invention is to address the problem that traditional photovoltaic tiles mostly have rectangular strip purlins on both sides that match the mounting frame. After the purlins are embedded in the mounting frame, they are fastened with bolts. This bolt-point contact fixing method results in a small contact area between the fixing component and the photovoltaic tile, with the stress concentrated at a single point or local area, leading to uneven stress distribution and causing local deformation or even cracking, thus affecting the service life and installation stability of the photovoltaic tile. Therefore, this invention proposes a quick-install fixing component and photovoltaic tile.

[0004] To achieve the above objectives, the present invention employs the following technology for a quick-install fastener: The device includes a fixing mechanism, which includes a housing. Mounting cavities matching the trough positions of the corrugated surface of the photovoltaic tile are fixedly installed on both sides of the housing. At least one first through hole is opened on the surface of the mounting cavity. The mounting cavity contains a sliding table that is slidably embedded in a plurality of symmetrically arranged sliding grooves. A positioning pin is fixedly installed between two symmetrical sliding tables. An adjustment mechanism is provided in the mounting cavity to push the positioning pin through the first through hole. The adjustment mechanism includes two first turntables rotatably embedded in the mounting cavity. The surface of the first turntable is provided with a guide groove for the slide table to pass through. A rotating mechanism for driving the first turntables to rotate is provided in the middle of the mounting cavity. When the guide groove rotates, it pushes the slide table to translate along the length of the groove. The rotating mechanism includes two horizontally movable sliding members symmetrically arranged inside the housing. When the distance between the two sliding members increases, it can drive the first turntable to rotate.

[0005] As a further description of a quick-release fastener of the above-mentioned technology: The adjustment mechanism also includes a rotating rod rotatably disposed in the middle of the mounting cavity, a guide groove connected to one end of the rotating rod, and a second turntable connected to the other end of the rotating rod; A spring is wound around the surface of the rotating rod, with one end of the spring connected to the mounting cavity and the other end attached to the surface of the second turntable.

[0006] As a further description of a quick-release fastener of the above-mentioned technology: The rotating mechanism includes two sliding members disposed in the housing. The sliding members are slidably embedded in the housing via slide rails on both sides. The sliding members are provided with abutment cavities, and the inner wall of the abutment cavity is provided with at least one deflection groove. The second turntable is slidably embedded in the abutment cavity and has a guide shaft embedded in the deflection groove on its surface.

[0007] As a further description of a quick-release fastener of the above-mentioned technology: The distance between the two sliding members is adjusted by a pushing mechanism, which includes abutment grooves formed on the two sliding members and abutment blocks that are slidably embedded in the abutment grooves. The inner wall of the abutment groove is in contact with the abutment block and the inner wall of the abutment groove is set to gradually narrow from top to bottom.

[0008] As a further description of a quick-release fastener of the above-mentioned technology: The pushing mechanism also includes a bolt groove in the middle of the housing and a bolt that is rotatably engaged in the bolt groove. A sleeve is fitted on the surface of the bolt, and two abutment blocks are respectively installed on both sides of the sleeve. Both of the aforementioned abutment grooves are provided with annular grooves having the same outer diameter as the kit and bolt grooves.

[0009] This application also provides a photovoltaic tile, including a quick-install fastener and a photovoltaic tile body. The photovoltaic tile body includes a photovoltaic section with an arc-shaped undulating structure on its surface and mounting sections disposed on both sides of the photovoltaic section. At least one positioning hole corresponding to the position of the first through hole and the positioning pin is provided on the surface of the mounting section.

[0010] As a further description of one type of photovoltaic tile of the above technology: The mounting part is provided with a limiting mechanism for pre-fixing the mounting cavity. The limiting mechanism includes at least two rotating grooves opened on the mounting part. A rotating ring is rotatably embedded in the rotating groove. A positioning plate is provided on the rotating ring and abuts against the end of the mounting cavity. A second through hole is opened on the surface of the rotating ring after rotation, which corresponds to the position of the positioning hole and the first through hole.

[0011] As a further description of one type of photovoltaic tile of the above technology: After the rotating ring rotates, it combines with the mounting part to form an annular cavity with the same inner diameter as the outer diameter of the mounting cavity.

[0012] As a further description of one type of photovoltaic tile of the above technology: The rotating ring has a storage cavity on its surface, and a bracket is rotatably embedded in the storage cavity. The end of the bracket is set to be arc-shaped to abut against the surface of the photovoltaic part.

[0013] As a further description of one type of photovoltaic tile of the above technology: The photovoltaic tile body is fixedly installed on the roof by a photovoltaic tile mounting frame. The photovoltaic tile mounting frame includes a frame that can be rotatably installed on the roof. At least one pair of first clips that abut against the photovoltaic part and a second clip that abut against the installation part are symmetrically arranged on the frame. The housing is fixedly installed on the second clip, and the second clip has at least one third through hole that cooperates with the positioning pin.

[0014] One of the above technical solutions has the following advantages or beneficial effects: 1. By setting a fixing mechanism, the photovoltaic tile body is pre-positioned by embedding the mounting cavity into the mounting part. Since the contact surface between the mounting cavity and the mounting part is set as an arc surface that matches the trough contour of the mounting part, the effect of replacing the traditional bolt point contact with surface contact is achieved. The concentrated stress is dispersed to the contact surface of the entire trough of the mounting part, and the stress distribution is more uniform, thereby avoiding the purpose of local deformation and cracking of the photovoltaic tile body. As the first turntable rotates, the four positioning pins in the mounting cavity pass through at least two of the first through hole, the second through hole, the positioning hole and the third through hole in sequence. At the same time, the bolt rotates to the deepest part of the bolt groove and completes the tightening. The photovoltaic tile mounting frame and the photovoltaic tile body are combined by the fixing mechanism. 2. Through the adjustment mechanism, rotation mechanism, and pushing mechanism, the bolt is tightened by rotation to penetrate the bolt groove. The bolt drives the abutment block to press down and push the inner wall of the abutment groove through the kit. Since the inner wall of the abutment groove is designed to gradually narrow from top to bottom, the abutment grooves and sliding parts on both sides can move synchronously under the push of the abutment block. When the sliding parts move, the guide shaft rotates along the opening trajectory of the deflection groove under the guidance of the deflection groove, causing the guide shaft to drive the second turntable to rotate. The second turntable drives the first turntable to rotate through the rotating rod, while shortening the distance between the second turntable and the mounting cavity and compressing the spring. When the first turntable rotates, it pushes the slide table to move horizontally along the length of the slide groove through the guide groove. The two slide tables drive the positioning pin to move out of the mounting cavity through the first through hole and pass through the second through hole and the third through hole in sequence. The second clamp and the mounting part are connected through the mounting cavity and the positioning pin. Attached Figure Description

[0017] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a quick-install fastener and a photovoltaic tile according to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] To address the issue that traditional photovoltaic (PV) tiles typically have rectangular purlins on both sides that match the mounting frame, and these purlins are embedded in the frame and then secured with bolts. This point-contact fixing method results in a small contact area between the fastener and the PV tile, concentrating stress at a single point or localized area, leading to uneven stress distribution and potentially causing localized deformation or even cracking. This negatively impacts the lifespan and installation stability of the PV tile. This invention proposes a quick-install fastener and a PV tile, such as... Figure 1 - Figure 15 As shown: Including the photovoltaic tile body 50, such as Figure 1 and Figure 2 As shown, the photovoltaic tile body 50 includes a photovoltaic part 51 with an arc-shaped undulating structure on its surface and mounting parts 52 disposed on both sides of the photovoltaic part 51. Three positioning holes 53 are provided on the surface of the mounting parts 52. like Figure 5 and Figure 6As shown, the photovoltaic tile body 50 is fixedly installed on the roof by the photovoltaic tile mounting frame 70. The photovoltaic tile mounting frame 70 includes a frame 71 that can be rotatably installed on the roof. At least one pair of first clips 72 that abut against the photovoltaic part 51 and second clips 73 that abut against the mounting part 52 are symmetrically arranged on the frame 71. like Figure 3 and Figure 4 As shown, the mounting part 52 is provided with a limiting mechanism 60 for pre-fixing the mounting cavity 12. The limiting mechanism 60 includes at least two rotating grooves 61 opened on the mounting part 52. A rotating ring 62 is rotatably embedded in the rotating groove 61. A positioning plate 66 is provided on the rotating ring 62 and four second through holes 63 are opened on its surface. By rotating the rotating ring 62, the rotating ring 62 and the positioning plate 66 can rotate under the restriction of the rotating groove 61 and combine with the mounting part 52 to form an annular cavity.

[0019] Furthermore, such as Figure 3 As shown, in order to restrict the position of the rotating ring 62 so that it cannot continue to rotate in the rotating groove 61, a receiving cavity 64 is provided on the surface of the rotating ring 62. A bracket 65 is rotatably embedded in the receiving cavity 64. The end of the bracket 65 is set to be arc-shaped to abut against the surface of the photovoltaic part 51. After the rotating ring 62 rotates to the designated position, the second through hole 63 can be perpendicular to the positioning hole 53 and the third through hole 731. At this time, the bracket 65 is rotated so that the bracket 65 rotates out of the receiving cavity 64 and the end of the bracket 65 abuts against the surface of the photovoltaic part 51, so that the position of the rotating ring 62 can be restricted in one direction. At the same time, in order to improve the effect of unidirectional restriction, the mass of the side of the rotating ring 62 with the bracket 65 is greater than that of the side without the bracket 65, so that the bracket 65 can actively abut against the surface of the photovoltaic part 51 under the action of gravity.

[0020] like Figure 7 As shown, in order to fix the photovoltaic tile body 50 onto the photovoltaic tile mounting bracket 70, the second clip 73 is provided with a fixing mechanism 10, such as... Figure 8 and Figure 9 As shown, the fixing mechanism 10 includes a housing 11, and mounting cavities 12 that match the trough positions of the mounting portion 52 are fixedly installed on both sides of the housing 11. By embedding the mounting cavity 12 into the mounting portion 52, the position of the photovoltaic tile body 50 is pre-positioned. Since the contact surface between the mounting cavity 12 and the mounting portion 52 is set as an arc surface that matches the trough contour of the mounting portion 52, the effect of replacing the traditional bolt point contact with surface contact is achieved, and the concentrated stress is dispersed to the contact surface of the entire trough of the mounting portion 52, resulting in a more uniform stress distribution. This achieves the purpose of avoiding the cracking of the photovoltaic tile body 50 due to local deformation. At least one first through hole 121 is opened on the surface of the mounting cavity 12. like Figures 10-12As shown, a slide table 14 is slidably embedded in the mounting cavity 12 through a plurality of symmetrically arranged slide grooves 13. A positioning pin 15 is fixedly installed between two symmetrical slide tables 14. The second clip 73 has two third through holes 731 that cooperate with the positioning pin 15. An adjustment mechanism 20 is provided in the mounting cavity 12 to push the positioning pin 15 through the first through hole 121. The adjustment mechanism 20 includes two first turntables 21 that are rotatably embedded in the mounting cavity 12. The surface of the first turntable 21 has a guide groove 22 for the slide table 14 to pass through. A rotating rod 23 is rotatably set in the middle of the mounting cavity 12. The guide groove 22 is connected to one end of the rotating rod 23. The other end of the rotating rod 23 is connected to a second turntable 24. A spring 25 is wound on the surface of the rotating rod 23. One end of the spring 25 is connected to the mounting cavity 12, and the other end is attached to the surface of the second turntable 24. When the second clip 73 and the mounting part 52 need to be connected by the fixing mechanism 10, the mounting cavity 12 is first embedded in the mounting part 52 and the end of the mounting cavity 12 abuts against the positioning plate 66. The positioning plate 66 positions the mounting cavity 12. Then, the rotating ring 62 is rotated, so that the rotating ring 62 rotates under the restriction of the rotating groove 61 and cooperates with the mounting part 52 to form an annular cavity with the same inner diameter as the outer diameter of the mounting cavity 12. At this time, the mounting part 52, the rotating ring 62 and the mounting cavity 12 cooperate to pre-fix the position of the photovoltaic tile body 50. Then, by rotating the first turntable 21, the first turntable 21 pushes the slide table 14 to move horizontally along the length direction of the slide groove 13 through the guide groove 22. The two slide tables 14 drive the positioning pin 15 to move out of the mounting cavity 12 through the first through hole 121 and pass through the second through hole 63 and the third through hole 731 in sequence. The second clip 73 and the mounting part 52 can be connected through the mounting cavity 12 and the positioning pin 15.

[0021] At the same time, such as Figures 13-14As shown, in order to enable the first turntable 21 to rotate, a rotating mechanism 30 for driving the first turntable 21 to rotate is provided in the middle of the mounting cavity 12. The rotating mechanism 30 includes two horizontally movable sliding members 32 symmetrically arranged in the housing 11. The sliding members 32 are slidably embedded in the housing 11 by slide rails 33 on both sides. The sliding members 32 are provided with abutment cavities 34, and the inner wall of the abutment cavity 34 is provided with at least one deflection groove 35. The second turntable 24 is slidably embedded in the abutment cavity 34 and the surface is provided with a guide shaft 31 embedded in the deflection groove 35. By pushing the two sliding members 32 towards When the relative directions are moved to increase the distance between the two sliding members 32, the sliding member 32 drives the deflection groove 35 to contact the guide shaft 31 provided on the second turntable 24 through the abutment cavity 34. Under the guidance of the deflection groove 35, the guide shaft 31 rotates along the opening trajectory of the deflection groove 35, so that the guide shaft 31 can drive the second turntable 24 to rotate. The second turntable 24 drives the first turntable 21 to rotate through the rotating rod 23. At the same time, the distance between the second turntable 24 and the mounting cavity 12 is shortened and the spring 25 is squeezed. The spring 25 undergoes elastic deformation, thereby achieving the purpose of actively controlling the rotation of the first turntable 21.

[0022] To achieve the goal of simultaneously controlling the synchronous movement of the two sliding members 32, such as Figures 13-15 As shown, the distance between the two sliding members 32 is adjusted by the pushing mechanism 40. The pushing mechanism 40 includes an abutment groove 41 formed on the two sliding members 32 and an abutment block 43 that is slidably embedded in the abutment groove 41. The inner wall of the abutment groove 41 fits against the abutment block 43 and the inner wall of the abutment groove 41 is set to gradually narrow from top to bottom. In addition, a bolt groove 45 is provided in the middle of the housing 11, and a bolt 44 is rotatably engaged in the bolt groove 45. A sleeve 42 is fitted onto the surface of the bolt 44, and two abutting blocks 43 are respectively installed on both sides of the sleeve 42. After the sleeve 42 is fitted onto the bolt 44, since both abutting grooves 41 have annular grooves with the same outer diameter as the sleeve 42 and the bolt groove 45, the bolt 44 is inserted into the bolt groove 45, and the sleeve 42 is embedded in the annular groove. The sleeve 42 drives the abutting blocks 43 to be embedded into the groove formed by the two abutting grooves 41. By rotating and tightening, the bolt 44 is made to penetrate deeper into the bolt groove 45. The bolt 44 drives the abutting blocks 43 through the sleeve 42. 3. Press down and push the inner wall of the abutment groove 41. Since the inner wall of the abutment groove 41 is set to gradually narrow from top to bottom, the abutment grooves 41 and the sliding parts 32 on both sides can move synchronously under the push of the abutment block 43 and drive the first turntable 21 to rotate through the deflection groove 35. As the first turntable 21 rotates, the four positioning pins 15 in the mounting cavity 12 pass through at least two of the first through hole 121, the second through hole 63, the positioning hole 53 and the third through hole 731 in sequence. At the same time, the bolt 44 rotates to the deepest part of the bolt groove 45 and completes the fastening. The photovoltaic tile mounting bracket 70 and the photovoltaic tile body 50 are combined by the fixing mechanism 10. When the photovoltaic tile body 50 needs to be removed, the bolt 44 is rotated in the opposite direction to move it out of the bolt groove 45. Under the push of the elastic deformation recovery of the spring 25, the distance between the two sliding parts 32 is shortened. The abutment cavity 34 moves in the opposite direction and drives the first turntable 21 to reverse through the deflection groove 35. The slide table 14 drives the positioning pin 15 to move in the opposite direction and be put into the installation cavity 12. At the same time, the abutment block 43 is pushed by the abutment grooves 41 on both sides and rises together with the bolt 44 until it is completely removed. At this time, the two abutment grooves 41 fit together.

[0023] Working principle: The photovoltaic tile body 50 is fixedly installed on the roof by the photovoltaic tile mounting bracket 70. By rotating the rotating ring 62, the rotating ring 62 and the positioning plate 66 are rotated under the restriction of the rotating groove 61 and combined with the mounting part 52 to form an annular cavity. After the rotating ring 62 rotates to the designated position, the second through hole 63 can remain perpendicular to the positioning hole 53 and the third through hole 731. At this time, the bracket 65 is rotated so that the bracket 65 rotates out of the storage cavity 64 and the end of the bracket 65 abuts against the surface of the photovoltaic part 51, thereby unidirectionally restricting the position of the rotating ring 62, so that the mounting cavity 12 is embedded in the mounting part 52 to achieve the pre-positioning of the photovoltaic tile body 50. When it is necessary to connect the second clip 73 and the mounting part 52 through the fixing mechanism 10, the mounting cavity 12 is first embedded in the mounting part 52 and the end of the mounting cavity 12 abuts against the positioning plate 66, and the position of the mounting cavity 12 is positioned by the positioning plate 66. Rotate the rotating ring 62 so that the rotating ring 62 rotates under the restriction of the rotating groove 61 and combines with the mounting part 52 to form an annular cavity with the same inner diameter as the outer diameter of the mounting cavity 12. At this time, the mounting part 52, the rotating ring 62 and the mounting cavity 12 cooperate with each other to pre-fix the position of the photovoltaic tile body 50. The bolt 44 is tightened by rotating it so that it goes into the bolt groove 45. The bolt 44 drives the abutment block 43 to press down and push the inner wall of the abutment groove 41 through the kit 42. Since the inner wall of the abutment groove 41 is set to gradually narrow from top to bottom, the abutment groove 41 and the sliding member 32 on both sides can move synchronously under the push of the abutment block 43. When the sliding member 32 moves, the guide shaft 31 rotates along the opening trajectory of the deflection groove 35 under the guidance of the deflection groove 35, causing the guide shaft 31 to drive the second turntable 24 to rotate. The second turntable 24 drives the first turntable 21 to rotate through the rotating rod 23. At the same time, the distance between the second turntable 24 and the mounting cavity 12 is shortened and the spring 25 is squeezed. When the first turntable 21 rotates, it pushes the slide table 14 to move horizontally along the length direction of the slide groove 13 through the guide groove 22. The two slide tables 14 drive the positioning pin 15 to move out of the mounting cavity 12 through the first through hole 121 and pass through the second through hole 63 and the third through hole 731 in sequence. The second clamp 73 and the mounting part 52 are connected through the mounting cavity 12 and the positioning pin 15. As the first turntable 21 rotates, the four positioning pins 15 in the mounting cavity 12 pass through at least two of the first through hole 121, the second through hole 63, the positioning hole 53 and the third through hole 731 in sequence. At the same time, the bolt 44 rotates to the deepest part of the bolt groove 45 and completes the fastening. The photovoltaic tile mounting bracket 70 and the photovoltaic tile body 50 are combined by the fixing mechanism 10.
